In an editorial related to the study published in the same issue of JAMA, oncologists Henry Lai, M.D., and Lennart Hardell, M.D., of the University Hospital in Orebro, Sweden, pointed out one possible
avenue for further exploration: "An important question is whether glucose metabolism in the brain would be chronically increased
from regular use of a wireless phone with higher radiofrequency energy than those used in the current study. Potential acute
and chronic health effects need to be clarified."
